‼️🚨 You probably want DeterminateSystems/determinate!

This repository used to provide NixOS, nix-darwin, and Home Manager modules for installing "Determinate Nix." However, it has always actually shipped Nix from upstream. Instead of making it silently switch users over to a different Nix, we've replaced the modules with assertions to help people move.

Migrating

Migrating for nix-darwin users

Determinate Nix is fully compatible with nix-darwin.

To fix this issue:

1. Install Determinate Nix with the macOS package from https://docs.determinate.systems/
2. Set nix.enable = false in your nix-darwin configuration
3. Delete the DeterminateSystems/nix reference from your flake inputs,
4. Delete nix.darwinModules.default from your nix-darwin modules list
5. Rebuild your nix-darwin configuration

Migrating for NixOS users

Determinate Nix is fully compatible with NixOS.

To fix this issue, please:

1. Replace the DeterminateSystems/nix flake input with:

inputs.determinate.url = "https://flakehub.com/f/DeterminateSystems/determinate/*";

2. Replace the nix.nixosModules.default module in your NixOS modules list with:

determinate.nixosModules.default

1. Rebuild your NixOS configuration, passing some extra options so you don't have to compile Determinate Nix yourself:

sudo nixos-rebuild \
  switch \
  --option extra-substituters https://install.determinate.systems \
  --option extra-trusted-public-keys cache.flakehub.com-3:hJuILl5sVK4iKm86JzgdXW12Y2Hwd5G07qKtHTOcDCM= \
  --flake ...

For more details, see our installation guide.

Migrating for home-manager users

Determinate Nix doesn't offer a home-manager module, because it must be configured at the host level.

Install or configure Determinate Nix on your system with our getting started documentation.
